移动代理系统中恶意主机攻击模型的研究

作为一种新的分布式计算模式，移动代理技术具有广泛的应用前景。但在目前的移动代理系统中，恶意主机问题，即保护代理免受恶意主机的攻击是很棘手的问题。为了更好地理解该问题，我们提出了基于抽象机器模型的攻击模型（RASPS）。该模型有助于提出有效的移动代理保护方案，并可以作为评价各种保护方案的基础。本论文首先分析了恶意主机的攻击行为，并在此基础上提出了恶意主机的攻击模型，最后分析了攻击实例程序。

Malicious Hosts Problem and Model of Attacks against Mobile Agents in Mobile Agent Systems

As a new distributed computing technology, mobile agent has a wide application prospect. But in current mobile agent systems, malicious hosts problem, namely protection of mobile agent against malicious hosts is a tough problem. To better understand this problem, this paper puts forward an attack model. This model helps to find effective solutions of this problem and work as a basis to evaluate various solutions. First, this paper analyses the attack behaviors of malicious hosts; then puts forward the attack model ;finally interprets an attack instance program.
